Abstract Complex power quality disturbance events contain multiple related basic events and disturbance event sources.Based on the analysis of the types and spatial-temporal characteristics of complex disturbance events,this paper proposes a source localization method for complex power quality disturbance events.The atomic decomposition algorithm is used to detect disturbance events.And the disturbance interval division method according to the starting and ending time of each basic event is given.Then the superposition principle is used to analyze the instantaneous power.Therefore,based on the polarity of disturbance energy,the source localization method for each disturbance section is proposed.Results show that the method can achieve source location of complex power quality events.
